Paul’s great concern in Philippians is for fruitful gospel partners who give themselves to the work of gospel advance. But there is a threat to any partners’ fruitfulness, and that threat comes from shifting from the gospel of grace. In one of the most straight-talking of all New Testament passages, Paul warns us off any non-gospel that puts confidence in the flesh. Paul’s writing in this part of Philippians is not for the squeamish–but it will keep us safe!
Watch out!
Philippians 3:1-7
Righteousness Through Faith in Christ
Finally, my brothers, rejoice in the Lord. To write the same things to you is no trouble to me and is safe for you.
2 Look out for the dogs, look out for the evildoers, look out for those who mutilate the flesh. 3 For we are the circumcision, who worship by the Spirit of God and glory in Christ Jesus and put no confidence in the flesh— 4 though I myself have reason for confidence in the flesh also. If anyone else thinks he has reason for confidence in the flesh, I have more: 5 circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as to the law, a Pharisee; 6 as to zeal, a persecutor of the church; as to righteousness under the law, blameless. 7 But whatever gain I had, I counted as loss for the sake of Christ.
